Sore pubic bone area?

Hi ladies. I'm not sure how exactly to describe this. I am 19 weeks & 4 days pregnant with my first child. Today and some of yesterday I am noticing that I am sore when I stand up and walk in my pubic area. It's like the bones that are around the vagina. Is this normal? Sorry for the lack of a "proper" description of the area. Any insight is appreciated.
